Does converting EOT to WOFF2 reduce quality?

No, converting EOT to WOFF2 does not reduce quality. WOFF2 uses lossless compression, meaning the font outlines, glyphs, and visual appearance remain identical to the original. Only the file size changes.

What file size reduction should I expect?

You can expect a file size reduction of 50-70% when converting EOT to WOFF2. For example, a 150KB EMBEDDED OPENTYPE file typically compresses to around 45-75KB as WOFF2 due to Brotli compression.

Do WOFF2 fonts work in all browsers?

WOFF2 works in all modern browsers: Chrome 36+, Firefox 62+, Safari 11.1+, and Edge (all versions). It's not supported in IE11 or older browsers.

Will my font's OpenType features work after conversion?

Yes, all OpenType features are preserved during conversion. This includes ligatures, kerning pairs, alternate glyphs, small caps, and other advanced typography features. The conversion process adapts the container format while preserving all font data.

Can I convert commercial/licensed fonts?

You can convert commercial fonts for testing purposes, but you must purchase the appropriate web font license before using them on a live website. Font licenses are format-specific – a desktop license for one format doesn't automatically grant web usage rights. Always check your license agreement or contact the foundry.

How is EOT different from WOFF2?

Embedded OpenType (EOT) is a font format with specific use cases. Web Open Font Format 2 (WOFF2) is the most efficient web format with Brotli compression. Choose based on your target platform and requirements.

What's the best format for my use case?

For modern websites, use WOFF2 as your primary format. Provide WOFF as a fallback for older browsers. For desktop applications, consider TTF or OTF.

Can I convert variable fonts?

Yes, variable fonts can be converted between formats while preserving all variation axes and design space. The conversion maintains the font's interpolation capabilities. Ensure your target browsers support variable fonts (Chrome 62+, Firefox 62+, Safari 11+).

Frequently Asked Questions

Common questions about converting EOT to WOFF2

1Why convert EOT to WOFF2?

To fully modernize legacy web fonts. EOT only works in IE6-11 (obsolete). WOFF2 works in all modern browsers with superior compression (60-70% smaller than EOT). This is the best upgrade path for old IE-only fonts.

2How much smaller is WOFF2 than EOT?

WOFF2 is typically 40-60% smaller than EOT. A 150KB EOT becomes approximately 60-90KB as WOFF2. Brotli compression (WOFF2) is far superior to LZ compression (EOT). This dramatically improves page load performance.

3Will I lose IE11 support with WOFF2?

Yes, WOFF2 doesn't work in any IE version. Best practice: Convert EOT to both WOFF2 and WOFF. Use WOFF2 for modern browsers (95%+), WOFF for IE9-11 fallback (1%). This covers 99.9% of users optimally.

4Should I keep EOT files after converting to WOFF2?

Only if you must support IE6-8 (under 0.01% of traffic). For 99.99% of sites, use WOFF2 (modern browsers) + WOFF (IE9-11) and discard EOT. Check your analytics – if you have zero IE8 traffic, delete the EOT files.

5Does WOFF2 improve Core Web Vitals over EOT?

Absolutely. WOFF2's superior compression (40-60% smaller) means faster LCP (Largest Contentful Paint) and better page load scores. EOT's inefficient compression hurts performance. Switching to WOFF2 directly improves SEO and user experience.

6Can I convert EOT directly to WOFF2?

Yes, most converters support this. However, for best results, some recommend: EOT → TTF → WOFF2. This ensures proper conversion of all font tables. Either path works, but TTF intermediate step can catch conversion issues early.

7What's the best modern font stack from legacy EOT?

Convert EOT to: (1) WOFF2 for modern browsers, (2) WOFF for IE9-11 fallback, (3) TTF for desktop use. Serve WOFF2 first in @font-face, then WOFF. This modernizes everything while maintaining compatibility.

8Do all features work better in WOFF2 than EOT?

Yes! EOT has limited OpenType support, especially in old IE versions. WOFF2 fully preserves all features, and modern browsers actually render them correctly. You'll see better typography, ligatures, and kerning after upgrading from EOT.

Troubleshooting Common Issues

Solutions to problems you might encounter

WOFF2 is 40-60% smaller than EOT

This is great! WOFF2's Brotli compression is far superior to EOT's LZ compression. A 150KB EOT becomes approximately 60-90KB as WOFF2. This dramatically improves page load performance. This is the desired outcome, not a problem.

WOFF2 doesn't work in IE11

This is expected. WOFF2 doesn't work in any IE version. For IE9-11 support, also convert EOT to WOFF. Use: WOFF2 (modern browsers, 95%+) + WOFF (IE9-11 fallback). Skip EOT entirely unless you need IE6-8.

Conversion fails with DRM protection

EOT includes Microsoft's font DRM system. Some fonts are locked to prevent extraction. Check the original font license. Commercial fonts often prohibit converting EOT to modern formats without proper licensing.

Variable font data lost

EOT predates variable fonts and doesn't support them. If you need variable fonts, you need the original source font (TTF/OTF with variation data), not EOT. EOT cannot hold variable font information.

Should I delete my EOT files?

Yes, unless you need IE6-8 support (virtually nonexistent). Replace EOT with: WOFF2 (modern browsers, better compression) + WOFF (IE9-11 fallback). This covers 99.9% of users with better performance. EOT is obsolete.

When NOT to Use WOFF2

Scenarios where you should keep EOT or choose a different format

Must support IE11
Why not: WOFF2 doesn't work in IE11; need WOFF fallback
Use instead: Create both WOFF2 + WOFF from EOT for full coverage
You still need IE6-8
Why not: WOFF2 doesn't work in any IE version
Use instead: Keep EOT for IE6-8, add WOFF (IE9-11) + WOFF2 (modern)
Font editing needed
Why not: WOFF2 is delivery format; should have TTF source
Use instead: Convert EOT to TTF for editing, then to WOFF2 for web
